42CHAPTER 5: UPGRADING A BRIDGE/ROUTER USING THE
CAUTION: If you are running any other firmware version besides 2.0 or 2.1, you should upgrade the firmware after upgrading the software.
To upgrade the CEC firmware, follow these steps:
aMake sure there is a floppy diskette with write access in the floppy drive on the bridge/router. The diskette is formatted during the upgrade, so make sure that the contents of the diskette you intend to use can be overwritten. Perform a manually recoverable firmware upgrade using the option
bUpgrade your firmware to version 2.6 using:
bcmsysupgrade
<device>
After the firmware has been upgraded, the bridge/router reboots.
3Update your configuration files using:
bcmsysupgrade
4Copy the upgraded software to the bridge/router using:
bcmsysupgrade
5Test your new software using:
bcmsysupgrade
The bridge/router is rebooted, and the utilities confirm IP connectivity and that the expected version of software is running.
6Verify that your upgrade completed successfully.
To verify that the software is working properly, you can perform a set of operational integrity checks on the newly upgraded device. These may include:
■Some standard checks based on services active.
A basic service verification test can Ping to specific IP addresses.
■Connectivity checks based on network topology. Examples of a connectivity verification include:
■Checking the connectivity between devices on different networks, through designated bridge/routers.
■Testing typical device connections on terminals, printers, or hosts.
■Testing the connectivity with specific bridge/routers.
■Custom checks based on applications and typical network use.
For instance, you can check normal operation over the network and perform file transfers, as well as run traces on specific routes or check routing tables.
7Accept or reject the upgrade.
■If your upgrade completed successfully, accept your upgrade using:
bcmsysupgrade
■If the upgrade process failed to meet your verification criteria, reject your upgrade using:
bcmsysupgrade
The bridge/router is rebooted using the previous version of software.
